Invention Reference Number
The new process converts 2,3-butanediol (BDO) into alkenes for renewable fuel production and eliminates the need for external aldehyde input by generating aldehyde as a co-product. This method is more sustainable, energy-efficient, and scalable, providing a viable pathway for generating sustainable aviation fuel (SAF) and other biofuels and chemicals from renewable resources.
Description
BDO, a compound derived from biomass fermentation, has high potential as a biofuel feedstock. However, traditional separation methods are energy-intensive due to BDO’s high boiling point. This innovative process converts BDO into dioxolane intermediates formed in the presence of an acid catalyst and an aldehyde. The dioxolane can then be converted into alkenes. Unlike previous methods, this approach regenerates the aldehyde needed for the reaction, creating a self-sustaining process. The alkenes produced can be further processed into valuable fuels and products.
Benefits
- Sustainable and renewable: Utilizes BDO derived from renewable biomass fermentation processes.
- Energy-efficient separation: Reduces energy requirements by avoiding traditional distillation methods.
- Aldehyde recycling: Self-sustaining process with in-situ aldehyde regeneration which minimizes external chemical inputs.
- Scalable and cost-effective: Streamlines production, making it suitable for large-scale biofuel generation.
- Reduces environmental impact: Enables the production of green fuels and chemicals with a lower carbon footprint.
Applications and Industries
- Biofuel production: Conversion of BDO into alkenes as a precursor for renewable liquid fuels, including sustainable aviation fuel (SAF).
- Chemical manufacturing: Production of alkenes for use as intermediates in various chemical processes.
- Green chemistry: Adoption by industries focused on sustainable and renewable chemical processes.
